/* =========================================================
   PRAKTIS - dizaino sistema
   Demonstracinis beribus projektas. Tamsi, futuristinė, mėlyna/violetinė
   paletė su glassmorphism kortelėmis. Spalvos parinktos taip, kad tekstas
   prieš foną atitiktų WCAG AA (min. 4.5:1 įprastam tekstui, 3:1 dideliam
   tekstui / UI elementams) - kontrastas patikrintas skaičiavimu, ne akimis:
   --text-muted pakeista iš pradinės #6b7299 (kontrastas ~4.3:1, neatitiko)
   į #7b82ab (~4.9-5.4:1 prieš --bg ir --bg-elevated). Baltas tekstas ant
   pagrindinio --gradient-primary (mėlyna->violetinė, šviesi versija) duoda
   tik ~3.6-3.9:1, todėl mygtukams su tekstu naudojamas atskiras, patamsintas
   --gradient-btn (~6.2-6.6:1) - šviesusis gradientas liko tik dekoratyviams
   švytėjimams/kraštams, kur teksto nėra.
